Re-using yeast

Post by E J Gumby » Sun Sep 11, 2016 5:07 pm

Hi,

I'm just bottling a batch of London Pride clone in which I used yeast harvested from a couple of bottles of Bengal Lancer.
How do I go about saving the trub at the bottom of the bucket and re-using it?
Is it as simple as pouring it off into a sanitised PET bottle and chucking it in the freezer?


Cheers
Sean

Pretty much, except keep it in the fridge, not the freezer.


Leave some beer in the fermenter, swirl the fermenter to get the yeast into the beer, then pour into a sanitary container. Put a lid on either loose or use a venting cap, and place in fridge. Use within a month.

You want to get everything as sanitary as possible first - I use jam jars that I put in the pressure cooker, but you could also boil them.
Ingredients: Water, Barley, Hops, Yeast, Seaweed, Blood, Sweat, The swim bladder of a sturgeon, My enemies tears, Scenes of mild peril, An otter's handbag and Riboflavin.

I prefer to overbuild the starter, and simply decant the excess into a sanitised jam jar, which I keep in the fridge. Harvesting from the FV as described above is fine, but can be a bit of a pain if you've dry hopped.
